ATTACHMENT FOR Application filed May 4,

To all whom it may concern.

Be it known that ROBERT H. HUGHEY, a citizen of the United States, and aresident of Greenwood, in the county of Greenwood and State of SouthCarolina, has invented certain new and useful Improvements inAttachments for Spindle Bearings,- of which the following is aspecification.

This invention relates to an attachment for spindle bearings, thebearings being of the type employedfor rotatably supporting one end of abobbin spindle, such as used in spinning frames or machinery. Briefly,the construction of the conventional form of bearing of the type abovereferred to consists of a short post, a portion of which is providedwith a longitudinal bore adapted for receiving a-bobbin spindle, the endof the spindle being suitably seated in the lower end of the bore. Thebearing and spindle are positioned vertically and suitably secured in abase. The bobbin is suitably carried upon the upper end of the spindleand between the bobbin and bearing there is formed on the spindle aV-groove pulley about which there extends a belt for driving thespindle. The spindle is rotated at a high rate of speed and itsjournaled portion is continuouslyimmersed in suitable lubricating oilthrough an oil reservoir which is.

formed on the upper end of the post bearing. The reservoir issubstantially U-shaped in formation, one terminal terminating with thebearing and the other terminating in close proximity to the upper sideof the V- groove pulley. An oil opening is provided for the upper end ofthe reservoir and a cap adapted for forming a closure for said opening.The cap is so formed and mounted that when it is lowered its one endprojects sufficiently to limit the upward movement of the spindle byengaging the pulley carried by said spindle; also when the cap is liftedor raised the pulley is permitted to pass and the spindle freely removedfrom its hearing.

In practice, it has been found that the bobbin has a tendency to risefrom the spindle, and in order to overcome this the bobbin is usuallydriven down so that it may better grip the spindle. This makes the.bobbin diiiicult to remove and often the oil caps of the reservoirheretofore referred to are broken during the removal of the bobbin.After the cap has been broken thereis nothing to hold the belt fromrising upon the bobbin and doing considerable damage, nor

to prevent the spindle from being jerked out of its bearings.

With that heretofore recited in mind it is the object of the presentinvention to provide an attachment by which broken bearings may bequickly and easily repaired and when so repaired will serve to preventthe belt from rising on the bobbin of yarn.

It is also an object of the invention that the attachment be adapted tobe applied to unbroken bearings and serve asa preventative ofthepossible breakage or destruction heretofore mentioned.

Other objects will hereinafter appear.

The invention is illustrated by way of example in the accompanyingdrawings, in which:

Figure l is a front elevation of a bearing and spindle together with'thebobbin carried thereby and also showing my invention when applied,

Figure 2 is a transverse section on the line 22 of Figure 1,

Figure 3 is a top plan view of the attachment as when applied to the oilreservoirand associated parts being shown in dotted lines.

Referring to the drawings more particularly, 10 indicates a post bearingat the one end of which there is suitably ournaled the bobbin spindle l1and said bobbin spindle being properly seated upon its lower end in theusual manner. The upper end of the spindle has secured thereto a sleeve12, upon the lower end of which there is formed a V- grooved pulley 13adapted to accommodate a rope belt 13, and upon the upper end of saidsleeve there is suitably mounted and secured a bobbin 14.

On the upper end of the post bearing 10 there is formed aflange 15 whichis tapered into a hub like portion 16 at its upper side; also the postbearing 10 is provided with the threads 17 which accommodate a nut 18.The nut 18 and flange 15 serving to clamp the post bearing to a suitablebase as indicated at 19. The flange 15 and its extended hub portion 16has formed therewith a reservoir 21 which consists of a hollow U-shapedmember, the upper end of which is provided with an oil opening 22,Figure 2, and also provided upon said end is a cap 28 being I adapted tocover said opening and pivotally mounted for upward and downwardswinging movement. The cap 23 has a portion 24; which extends from theupper terminal of the reservoir 20 sufliciently to engage the one sideof the pulley 13, in case said pulley rises and in this manner limitsthe upward movement of the shaft 11.

To the structure heretofore recited I make no claim. i 7 My inventionconsists in an attachment for the reservoir and consists of a device asshown .in full lines in Figure 3. 7 Re ferring more particularly toFigure 3, indicates a U-shaped clip, the terminals. of which are formedwith suitable openings 26 whichare adapted to receive the screw bolt 2'7by which the member may be clamped about the reservoir 20 of the bearingpost 10 as shown in Figures 1 and 2. Upon one edge of the bridge portionof this U-shaped clip there is formed a plate like finger 28 which isslightly curved inwardly at its outer end as at 29; also there is formedwith the plate-like member 27 an outwardly curved portion 30 which hasan offset 81 in its outer end as shown.

The attachment is positioned as shown in Figures 1 and2 and the outerend of the finger 28 extends in close proximity to the one side of thepulley 13 and forms a substantial stop for said pulley and thusrestricting the upward movement of the spindle ll. The ofiset 30 permitsthe upward and downward swinging movement of the outer portion 24: ofthe cap 23, in case the attachment is applied to an unbroken reservoiror bearing.

I claim .1, In an attachment for a spinning spindle of thecharacterdescribed, comprisinga U- shaped clip having a finger extending from thebridge portion thereof, and means for connecting the ends of said clip.a

2. An attachment for spinning spindles of the character described,comprising a U- shaped clip, a screw bolt for connecting; the legterminals of said clip, and a platelike linger formed upon the one, edgeof the bridge portion of said clip and extending at substantially rightangles to the legs of the cli Ll In an attachment for spinning spindlesof the character described, comprising a U- shaped clip, a screw boltfor connecting the leg terminals of said clip, and a plate like fingerformed upon the one edge of the bridge portion of said clip, said fingerex tending at substantially right angles to the leg portions of saidclip and having its inner ends slightly curved inwardly.

4. In combination, a rotatable spindle, a pulley carried thereby aboutwhich passes a belt adapted for driving the spindle, a stationarysupport in close proximity to the spindle, and an attachment adapted tobe secured to the support and to prevent movement of the spindle in onedirection.

V 5. In combination, a vertical spindle, a post bearing for rotatablysupporting the lower end of said spindle, said post bearing having anextension formed'therewith serving as an oil reservoir and saidextension be ing in close proximity to the spindle, a pulley carried bythe spindle and positioned adjacent the postbearing and about which abelt passesfor rotating the spindle, and an attachment adapted to besecured to the extension of the post bearing and to serve for preventingupward movement of the spindle.

6. In combination, a rotatable spindle, a postbearing ior rotatablysupporting the lower end of said spindle, said post bearing having anextension formed therewith serving as an oil reservoir and saidextension being in closecproximity to the spindle, a pulley carriedbythe spindle and positioned adjacent the post bearing and aboutewhich abelt passes forrotating the spindle, an attachment adapted to be securedto the extension of the post bearing and to serve for preventing upwardmovement of the spindle, said attachment consisting in a U- shaped clip,the leg portions of which are adapted to straddle the oil reservoirextension of the post bearing, means for clamping the legs about the oilreservoir extension, and a linger extending from the bridge portion ofsaid clip adapted to be disposed in close proximity to the upper side ofthe pulley.
